Популярность набирают самоуплотняющиеся бетоны (СУБ). Преимуществом СУБ является высокая подвижность, поэтому акцент ставится на их реологических свойствах. Развитие технологии продолжается в легких самоуплотняющихся бетонах (ЛСУБ), сочетающих высокую подвижность и низкую плотность. Изучение ЛСУБ акцентируется на влиянии рецептуры на свойства смеси. Цель исследования — изучение влияния соотношения сухих компонентов на реологические свойства ЛСУБ на полых микросферах.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Объектом исследования приняты ЛСУБ на полых микросферах. Соотношение сухих компонентов менялось в зависимости от целевой плотности бетона. Состав включает: портландцемент, керамические микросферы, кремнеземистую добавку, фракционный песок (Пф), кварцевую муку (Пм), гиперпластификатор и воду. Количество воды и концентрация пластификатора приняты постоянными: 0,5 и 1,4 % соответственно. Получены результаты исследований реологических характеристик ЛСУБ. Ключевые реологические параметры — напряжение сдвига и вязкость.</p></sec><sec><title>Результаты</title><p>Результаты. Бетонные смеси плотностью 1400 кг/м3 имеют дилатантный характер течения вне зависимости от соотношения Пм/Пф. При плотности 1500 и 1600 кг/м3 характер течения сменяется на псевдопластичный при Пм/Пф == 25/75. Показана возможность управления типом течения тяжелых бетонов изменением Пм/Пф. Разница течения между легкими и тяжелыми бетонными смесями отражается на зависимостях напряжения сдвига и вязкости от Пм/Пф.Увеличение Пм повышает напряжения сдвига и вязкость у ЛСУБ, у тяжелых составов наблюдается смена нисходящей зависимости на восходящую в диапазоне Пм/Пф = 25/75–75/25 при разных скоростях сдвига.</p></sec><sec><title>Выводы</title><p>Выводы. Представлена возможность изменения реологического характера течения легких и тяжелых смесей при изменении исследуемых факторов. Выполнен сравнительный анализ реологических кривых с использованием уравнения Оствальда – Вейля для тяжелых и легких бетонных смесей. Рассмотрена роль дисперсности минерального заполнителя и полых микросфер в управлении реологическими свойствами исследуемых ЛСУБ.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Construction needs new concrete. Self-compacting concretes (SCC) are gaining popularity. The advantage of SCC is high mobility, so the emphasis is on their rheological properties. The technology continues to develop in lightweight self-compacting concretes, that combines high mobility and low density. The study of LWSCC (Light-weight self-compacting concrete) focuses on the effect of the formulation on the properties of the mixture. The purpose of this study is to investigate the effect of the ratio of dry components on the rheological properties of LWSCC on hollow microspheres.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The object of the study is LWSCC on hollow microspheres. The ratio of dry components varied depending on the target concrete density. The composition includes: Portland cement, ceramic hollow microspheres, silica additive, fractional sand (Sf), quartz powder (Sp), hyperplasticizer and water. The amount of water and the concentration of plasticizer are assumed to be constant: 0.5 and 1.4 %, respectively. The results of studies of the rheological characteristics of LWSCC were obtained. The key rheological parameters are shear stress and viscosity.</p></sec><sec><title>Results</title><p>Results. Concrete mixtures with a density of 1,400 kg/m3 have a dilatant flow pattern regardless of the Sp/Sf ratio. At densities of 1,500 and 1,600 kg/m3, the flow pattern changes to pseudoplastic at Sp/Sf = 25/75. The possibility of controlling the type of flow of heavy concrete by changing the Sp/Sf is shown. The difference in flow between lightweight and heavy concrete mixtures is reflected in the dependences of shear stress and viscosity on Sp/Sf. An increase in Sp increases the shear stresses and viscosity of LWSCC, for heavy compositions, a downward-to-upward relationship is observed in the range of Sp/Sf = 25/75–75/25 at different shear rates.</p></sec><sec><title>Conclusions</title><p>Conclusions. The possibility of changing the rheological character of the flow of lightweight and heavy mixtures with changes in the studied factors is shown. A comparative analysis of rheological curves using the Ostwald – Weil equation for heavy and light concrete mixtures has been performed. The role of the dispersion of mineral aggregate and hollow microspheres in controlling the rheological properties of the studied LWSCC is considered.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>самоуплотняющиеся бетонные смеси</kwd><kwd>полый заполнитель</kwd><kwd>мелкозернистый бетон</kwd><kwd>реология</kwd><kwd>напряжение сдвига</kwd><kwd>вязкость</kwd><kwd>уравнение Оствальда – Вейля</kwd><kwd>псевдопластическое течение</kwd><kwd>дилатантные течения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>lightweight self-compacting concrete</kwd><kwd>hollow aggregates</kwd><kwd>fine-grained concrete</kwd><kwd>rheology</kwd><kwd>shear stresses</kwd><kwd>viscosity</kwd><kwd>rheology</kwd><kwd>Ostwald – Weil equation</kwd><kwd>pseudoplastic flow</kwd><kwd>dilatant flow</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Данная работа выполняется в рамках реализации Программы развития федерального государственного бюджетного образовательного учреждения высшего образования «Национальный исследовательский Московский государственный строительный университет» на 2025–2036 годы.
